[PATCH v2] Input: synaptics-rmi4 - add missed operations in remove

[Chuhong Yuan]

The driver forgets to destroy workqueue in remove like what
is done when probe fails.
Add a call to destroy_workqueue to fix it.

Since unregistration will wait for the work to finish, we do
not need to deal with work in remove.
